Quick addedum to FAQ: Only newly-created events on handheld get pushed to Google Calendar. Appointments pre-existing when Google Sync is installed do not get pushed to Google Calendar, even if they're in the future, or modified subsequently updated. I didn't have a chance to check the reverse.

I wanted to clarify something I noticed today...I was reading this to mean that the appointment would have to be created on the BB in order for it to push to Google Calendar.

I had several meeting updates and additions sent to me today that I accepted on my work PC (Outlook). Those sync to my BB via BES, and the BB must have pushed them to my calendar via GooSync because they are now on my Google Calendar.
